关键技术是指在技术领域中占据重要地位、反映技术发展趋势并具有引领作用的重要技术。运用基于专利引文分析的关键路径方法、岛群方法和高被引方法以全息摄影技术领域为例对关键技术挖掘方法进行理论分析和实证研究,比较这三种方法在关键技术挖掘中的作用及局限,在此基础上探讨将这三种方法相结合进行关键技术挖掘的可行性。
Critical technology refers to the technology which occupies important position, reflects the technology trends and plays a leading role in the technology area. This paper proposed critical path method and island method to mine critical technology. This paper chooses G03H class from IPC to do an empirical research, and adopts high cited method, critical path method and island method to mine the critical technologies in this area and discusses the probability to combine those three methods to mine the critical technologies.
